UV-C Questions and Answers

A Powerful New Tool

UV-C offers a completely chemical free option to sanitizing an area. But what exactly is it and is it being used elsewhere? We have the answers.

Question: Do UV lights kill pathogens (viruses)?

Answer: Yes, ultraviolet light in the "C" range, also known as UV-C, has been known to kill pathogens of all types under varying circumstances. UV radiation kills viruses and bacteria by damaging their DNA and RNA (otherwise known as their genetic makeup). Of the three main types of UV light, UV-C, which has a wavelength range of 200 to 280nm, is the most effective for killing viruses, with the most effect wavelength being about 260 nm.

Question: What is the Germicidal Ultraviolet-C (GUVC) Light Process?

Answer: A completely chemical free solution to disinfecting areas of bacteria, viruses, germs and mold with a 99.9% success rate.

Question: Is UV-C being used to disinfect objects currently?

Answer: Yes. In New York City, the MTA will start using powerful ultraviolet lights to disinfect the subway cars and busses. The measures are part of the beefed-up sanitation program rolled out by the MTA to make the transit system cleaner and safer for all passengers. The efforts is part of a partnership with Columbia University and is one of the largest roll outs of its kind in regards to the UV light technology. Columbia University theorizes that UV light can be used to kill viruses and diseases found on the transit network.

At hospitals across the nation and world, UV lights are being used to disinfect equipment and hospital rooms to ensure that staff and patients are kept safe from harmful viruses that could potentially harm them.

Question: How Does UV Air Disinfection Help Combat Coronaviruses?

Answer: Coronavirus is highly vulnerable to germicidal UV irradiation. A study showed showed that the susceptibility of a coronavirus to UV light is greater than 3 times when compared to the influenza virus. The reason for this is that coronaviruses are commonly weaker in structure than typical flu viruses. (Walker, Chris & Ko, Gwangpyo. (2007).
